forlinaking and packing recrackers.

l"I'he objects of this invention are to provide a machine for binding a charge of powder centrally'within a tube and for binding such tube upon a sheet of cardboard for display and use.

Al particular 'object is to bend and compress intor theopen ends of such tubes flexible tongues from opposite sides of such sheets for thereby retainingsuch charges of powder within such tubes,

' and for retaining said tubes on such sheets both l by said tongues.

iiWith these and other objects to behereinafter stated I have illustratively exemplified my invention'by views and figures from drawings first led in said original application and particularly described as follows:

f'Figure 1`is aside elevation of the machine fer binding ihetongues i the homing sheet intol the ends of the container tubes, and also shows acarrier ybelt with several sheets of cardboardA .disposed upon the'same and vbunches of open ended tubes disposed upon several of said sheets.k -`-rFigure 2 is a plan view of the parts shown in- Fig. `1,Vand showing one separate sheet of cardboard with tongues divided along opposite edges thereof vand-all flatly disposed upon the belt, and severalw'other sheets with tubes positioned thereon. Y

*Figure 3 risv a cross section View of a portion of Fig. Ltaken on line 22, of Fig, 1.

Figure'lis a sectional fragmentary detail of a portion of Fig. 1, taken on line 23, of Fig. 1.

Like characters on the different figures represent like parts. h. represents open ended tubes into which charges of powder preferably in sacks with protruding fuses e, have been previously positioned vcentrally therein. I represents holders or packer sheets, preferably of thin cardboard material for mounting and sustaining such tubes in bunches thereon. J represents tongues divided by slits along opposite sides of the sheets adapted to` be bent into the ends of the tubes for retaining the charges of powder therein and for retaining the bunches of tubes upon the sheets.

(c1. sii-2o) gear may be turnedtogether with said shaft 11, Fig. 1, by any othersuitable source of power. Said belt is extended in loop fornr over said sprocket 16, and over a sprocket 83, at the opposite end of theframe, which latter sprocket is'vaxed upon stubshaft 84'.

Side rails 84 are provided for guides for the n sheets I. Floor plates 85W-areprovidedijbetween the rails and are spaced apart by a flat bar 86,

vwhich serves as a bed or bottom of a grooveor channel between the side frames 38", forithe belt 14. Saidbelt is provided with outstanding blades 15, suitably-spaced for onev orfmore of said `.sheets I, which latter lap over and beyond the channel, and upon the plates 85. Brackets 81 areattached to the inner side of the rails 84,

to keep the tubes upon the sheets centrally over f the channel as they are moved along with the sheets; and are spaced above the plates to permit the ends of the sheets -to passr between.

The front end of these brackets is located at a suitable distance from the front end of the frame 38 to provide a space where the sheets I and i tongues may be deposited upon thel belt between the blades 15. The rear end of the brackets terminate at a point where the slitted tongues of l the sheets are to beupturned, as next explained.

yOn each. side of said 'channel and suitably spaced 96 thereon, are horizontally mounted on shafts I 91, and 98, and thereby revolved in line with 38" represents a rectangular frame preferably in elevated position as ,on legs 38. 14 represents a conveyer belt for moving the sheets, which is slidably mounted longitudinally over the frame. This belt at one end is rotatably mounted over sprocket 16, which is afxed to a stub shaft 11,

the centers of the tubes, and are suitably regulated so that as the upturned sections of the sheets pass opposite the fingers, such tongues will be compressed by the -ingers into the open ends of the respective tubes h, as they are car- -ried along by said belt and blades thereon. The

several recrackers and sheets are thus combined into suitable packs and drop from the belt into any suitable receptacle.

The perpendicular yshafts for the crimper wheels, are driven by a bevel gear 99, affixed to the end of shaft 89. This drives gear |00 attached on a stub shaft |0|, and the latter turns another on which is afxed an actuating gear 18. Said gear |02, attached on the other end thereof,

whereby a gear |03 which is affixed to shaft 98, is turned and the crimper wheel 95, revolved. The oppositely positioned crimper wheel 95, is turned by a at gear wheel |04, attached to the shaft 98, which meshes with a similar flat gear H15, affixed to lower end of said shaft 91.

Variations may be made in the mechanism and in method of connecting and driving the Various parts, and I do not limit my invention to the specific construction shown in the drawings. It will be seen by reference to the drawings, that the above described chain 9|, for turning shaft 89, is driven by sprocket 92, affixed on shaft 84', which latter is rotated by the sprocket 83 and the carrier belt or chain 14.

Having described my invention I claim as new:
